HENRY C. PAYNE, OF WEBSTER CITY, IOYVA.

WASH-BOILER.

SPECIFICATION forming part of Letters Patent No. 354,212, dated December14, 1886.

Application filed January 30. 1886. Serial No. 190,279.

To all whom it may concern.-

Be it known that I, HENRY C. PAYNE, a

claim.

y Fig. 2 is a sectional view taken on the line 00 x of Fig. 1. Fig. 3 isa detail sectional view through one side of the boiler, at the upperedge thereof. Fig. 4 is a detail elevation of aportion of one side ofthe boiler, looking from inside; and Fig. 5 is a perspective view of theslide.

Referring to the drawings, in which similar letters of reference denotesimilar parts, A designates a wash-boiler having a cover, 13, the edgesof which project beyond the sides thereof to a point nearly in contactwith a flange, O which extends upwardly from the outer wall of theboiler to an elevation preferably higher than the wall of the boilerproper.

D designates ports formed in the sides of the boiler above the loweredge of the flange G, and D slides, also provided withports and rodswhich project through the flange, by means of which the ports of theslides are made to wholly or partly register with those in the side ofthe boiler. These slides are guided and supported by keepers d, whichare secured to the side of the boiler.

(No model.)

E designates ports formed in the cover B, which are provided withsliding covers 0.

The operation of my device is as follows: After being filled with water,850., and placed upon the stove the slides are pushed in, therebyclosing the ports in the side of the boiler. The port in the top of thecover is also closed by the lid 6, whereby the radiation of heat fromthe interior of the boiler and the entry of currents of cold air intothe space under the cover is avoided. Then the water boils andoverflows, the ports in the sides of the boiler and the cover may beopened. Usually the portsin the cover can be kept closed, allowing thesteam and water of condensation to escape through the side port, whichin rising strike the overhanging edge'of the. cover, which acts as asurfacecondenseiz. The water of condensation and the overflow of wateris kept in the chamber formed by said cover, the boiler, and flangeuntilit fiows back into the boiler.

Modifications in the details of construction may be inade withoutdeparting from the spirit or sacrificing the advantages of a rod orhandle to operate the same substantially as described.

I claim- In a wash-boiler, the combination of the following elements:the boiler A, having ports D, cover B, having an overhangingsurfacecondenser, flange C, a slide, D, and keepers d, substantially asdescribed.

In testimony whereof I affix my siguatu re in presence of two witnesses.

HENRY C. PAYNE.
